IS there a hard and fast rule out there for number of fish per litre/bag when shipping?

just trying to figure out a per box size/price for shipping clowns direct to LFS, saving me diesel and time! I have access to oxygen for shipping if needs be. most shops near me take about 20 fish a month, which i can have shipped quite cheaply.

why's a single bag risky?in theory i could bag them individually, but i dont see the point. one bag saves me time and unit cost. On shipments ive seen unboxed the only fish that come in individually are things like dottybacks or territorial species. speaking to some of the guys i work with they ship approx 100fish@ 1-3g in about 10l of water. Will speak to a couple of LFS over the weekend and see what they think.

Packing multiple stressed fish per bag would seem to be inviting the cross contamination of any disease that a wild caught fish might have.Still risky if the fish are pond (tank) raised but essentially in wild and potentially poorly filtered water.Captive bred would be less risky because of the controlled environment.

I have only shiped a couple of times myself by air but know a few people that do it as well It depends on how long they are going to be in the bag for as wellSay it was 6 to 7 hrs max i put 5 to 8 per bag the bags i use hold about 1.5l water and then 2/3 more is air Beter of spliting them into a few smaller bags than 1 big bag

Last time I unpacked a box of clowns from ORA(admittedly a few years ago), there were a bunch of fish in each bag. I don't recall exactly how many were in each bag, but it seems like there were probably at least 20 per bag.

I'm not saying that ORA is perfect, but they were doing it apparently without too much trouble (there were never any/many DOA's in the ORA shipments I unpacked)
